Blue Sreen of Death x3!

I have had this happen before but only ever once.

I turned up on site today where my desk has been sat for the last week being used every day. This morning I got the BSD 3 times when I switched it on.

The message said something like IRQL not less or equal to.

Can any technical people shed any light on this and is the stabilility of the desk at risk of being compromised?? Just to add the desk now it has started seems to be normal.

EDIT : Have just discovered one of the touch screens is not responding to touch... I'm guessing then the problem is related??

Cheers
